North Korea's high-level delegation returned home Sunday night after its three-day trip to South Korea.

The 22-member delegation, including North Korean leader Kim Jong-un's sister Kim Yo-jong and the North's ceremonial head of state Kim Yong-nam, departed on a North Korean plane from Incheon International Airport around 10:24 p.m.

The delegation wrapped up its trip after attending the North's Samjiyon orchestra’s second and final concert in Seoul, which started at 7 p.m. at the National Theater of Korea. 

President Moon Jae-in watched the concert along with Kim Yo-jong, Kim Yong-nam and head of the art troupe, Hyon Song-wol. 

Kim Yong-nam told Moon before the start of the performance that he could now return to his country carrying “hope that they will meet again” as platforms for such talks have been established. 

Moon in response, stressed inter-Korean cooperation while comparing the recent exchange to a “small spark” that could turn into a “full burning torch.”

The head of the art troupe sang a song about reunification in the later part of the show, and Seohyun from South Korean pop group Girls' Generation joined the North Korean performers for a song at the end of the concert.
